A Review on the Synthesis Methods of Nano Zero Valent Iron (NZVI)

Recently nano zero valent iron (NZVI) because of its unique electrical, magnetic, optical and catalytic properties and also because of its high surface area and activity, resulted from its small size, has been lionized. Rapid development in nanotechnology has caused increased number of research works about NZVI applications especially for environmental purposes. The synthesis method of nanoparticles is determinant parameter of their size and structure. Researchers have used various methods for NZVI synthesis. These methods are divided to chemical and physical categories. In the present study we review the synthesis methods of NZVI.
